Thread: 24mm end mill for 16mm collet?
12/04/2021 19:01:45

Boring head/bar for anything over 16mm imo

I've used a boring bar at high speed to 40+mm in steel

it comes off like gossamer with a fine feed  and leaves a nice finish

Thread: Laptop with a SD card slot

It frees up a usb slot which is more flexible

Thread: Distorted ship's hull steel panels
11/04/2021 07:34:31
Posted by Bill Pudney on 10/04/2021 23:38:36:

I was told by someone who would know that about seven tonnes of epoxy filler is used to smooth out the hull on your average frigate, this improves performance and reduces the hull generated noise.

I never knew about this but the moment I read it it made perfect sense

There are also coatings on the upper decks which reduce radar reflectivity/signature

edit

The usas sooper destroyer had such a small radar signature it was a navigation hazard.

At night other vessels thought it was a small fishing boat, not a full sized ship

I can only talk about ships,

the royal navy ones would be as light as possible compared to merchant ships so this may account for some of the panel distortion

They are basically big speedboats with guns

Current policy is the 99 caveats system so be careful before you receive money because you may be signing an agreement to repay it if one of the 99 caveats is breached

Thread: Anti seize grease on Myford spindle nose?
07/04/2021 08:54:06

Just run your lathe backwards on the backgear by hand to unstick a chuck

I put a block of wood braced on the bed under a chuck jaw and voilla!

With a backgear lathe you never have a stuck chuck

I have put a bar in the oil hole of the pulley to give me more control

Time is like a toilet roll, the older it gets the faster it goes

Thread: The Moon
03/04/2021 06:42:32

Used to take a lot of sights for navigation using anything and everything to while away the time at sea but I stopped using the moon because it's a stellar ferrari compared to anything else you look at up there

Thread: CNC - What's the Problem?
01/04/2021 06:53:25

It's a bit like with cars

When cheaper self driving CNC versions become available will we all race off to buy one?

How much fun is it to push a button?

It's not about the destination, it's about the journey

drummond chuck1.jpg

30/03/2021 10:56:01

Re: your narrow chuck work

No-one mentioned it but a recent ebay sale had the amazingly rare drummond 4jaw which was specially developed for large work bigger than the chuck itself, to fit into the gap

The jaws appear to be quite small compared to the chuck body

Thread: 1.1 kw brushed motor Torque
30/03/2021 09:40:29

If you really want torque you must use backgear on a hobby lathe

Quickie jobs are not a big deal but if you need it for any length of time then backgear is the only way

Thread: Lathe Rigidity Issues - Modification Opinions

Forgot about a Drummond mod which noticeably improved spindle stiffness

Thread: Excellent Chinese Chuck
28/03/2021 06:13:58

sanou seem to be flavour of the month at the moment. They supplied all the keyless chucks on Aldi Scheppach and Lidl bench drills recently

Runout wasn't particularly brilliant but they are nice solid bits of kit that do the job

They may have connections with and be doing work for Rohm

Thread: Removing a J2 arbor from a drill chuck
27/03/2021 13:51:01

It's problably glued in and dismantling would make the job a lot easier

Track rod ends are similar and you can either use a big hammer or jury rig a joint separator
